Laurent, thanks for bringing this up (I know it is something you
mentioned in the past).  I like the idea of marking the functions in
the cdfpackages using .Deprecated() for this release.  In the next
cycle they can be .Defunct() and then gone.

I realize it likely overkill, but sticking to the deprecation cycle is
a good policy -- and if nobody is using them anyway, then the masking
isn't going to bite anyone :-)

Someone should send a note to the bioconducter list and announce that
these functions will be deprecated in the upcoming release (and
mention that there are alternatives in affy).
